I have been given figures for a pension actuarially reduced if I claim it at 60 this year. I have the factor they used. The normal end age is 67. I want to work out how much more the amount would be if I defer it 1/2/3/4/5/6/7 years to inform when I decide when to take it. Is there a simple formula to work this out or is it more complicated? I'm going a bit number blind.
